Functional Description
The CY7C1460KV33/CY7C1460KVE33/CY7C1462KVE33 are
3.3 V, 1M × 36, and 2M × 18 synchronous pipelined burst SRAMs
with No Bus Latency™ (NoBL logic, respectively. They are
designed to support unlimited true back-to-back read/write
operations with no wait states. The
CY7C1460KV33/CY7C1460KVE33/CY7C1462KVE33 devices
are equipped with the advanced (NoBL) logic required to enable
consecutive read/write operations with data being transferred on
every clock cycle. 6
This feature dramatically improves the throughput of data in
systems that require frequent write and read transitions. The
CY7C1460KV33/CY7C1460KVE33/CY7C1462KVE33 devices
are pin-compatible and functionally equivalent to ZBT devices.
All synchronous inputs pass through input registers controlled by
the rising edge of the clock. All data outputs pass through output
registers controlled by the rising edge of the clock. The clock
input is qualified by the clock enable (CEN) signal, which when
deasserted suspends operation and extends the previous clock
cycle.
Write operations are controlled by the byte write selects
(BWa–BWd for CY7C1460KV33/CY7C1460KVE33 and
BWa–BWb for CY7C1462KVE33) and a write enable (WE) input.
All writes are conducted with on-chip synchronous self-timed
write circuitry.
Three synchronous chip enables (CE1, CE2, and CE3) and an
asynchronous output enable (OE) enable easy bank selection
and output tristate control. To avoid bus contention, the output
drivers are synchronously tristated during the data portion of a
write sequence.
